15 cnam. (ci. ca -41) This invention relates to optical devices and more particularly has reference to telescope goggles comprising telescope units mounted in a goggle frame whereby the wearer is selectively provided with vision through the telescope units or through the goggle lenses.

This invention is an improvement upon the telescopic goggles described and claimed in Patent 1,892,444 of December 27, 1932 to Carl L.

l0 Bausch. In that 'patent the telescopes are fastened in fixed relation to the goggle lenses and hence there is no provision for adjustment for interpupillary distance or inclination.

One of the objects of my invention is to provide an improved and adjustable telescope goggle. Another object is to provide an improved means for mounting a telescope upon a goggle frame. A further object is to provide an improved connection between the telescope and the goggle lens.

A further object is to provide means whereby a commercial type goggle can be readily converted into telescope goggles. These and other objects and advantages reside in certain novel features of construction, arrangement and combination of parts as will hereinafter be more fully set forth and pointed out in the appended claims.

In the drawings:

One embodiment of my invention is shown in the drawings wherein Ill indicates, generally, a pair of goggles such as are worn by aviators,

5 autoists, and the like. 'I'his goggle has two eye units each comprising a substantially ovalshaped, split frame member l I, the adjacent ends of which are secured by means of a suitable latch l2. The two eye units are pivoted to the ends of a bracket I3 which forms the bridge ot the goggles and each frame member Il carries a sponge rubber pad 14.

The frame member Il is provided .with a grooved portion I5 in which is mounted the ovalshaped member li shown in Fig. 6. The mem- 5 ber I6 comprises three rim portions ll, Il and I9 which are secured, as by soldering, for example, to a plate 20 having an aperture 2l. I'he rim portions Il, I8 and I9 have inner grooves in which is mounted the lens 22, which, ot course. l0 is cut away to provide for the plate member 20 as shown in Fig. 1.

Fastened to the bracket I3 by means o! screws 23 is a split ring 24 in which the cylindrical tubular member 25 is rotatably mounted. A l5 screw 26 having a knurled head 2l serves to bring the ends of the split ring 24 together to clamp the tubular member 26 against rotation. A square tubular member 28 is ilxed within the tubular member 25 and extends laterally to re- 20 ceive the square rods 28. Each rod 29 terminates in a ring 30 and hasa threaded hole 3l to receive a screw 3l' which extends through a slot 32 near the end of the tubular member 28 and terminates in a knurled head 33. 26

Each ring 30 carries aGalilean telescope comprising a tube 34 provided with a threaded section 35 for receiving the positive lens cell 3l which is locked into position by a locking ring 31. The tube 34 has a secondthreaded section 30 38 for receiving-the negative lens cell' 39. A shoulder 40 is formed on the negative lens cell A3i) which serves to clamp the' telescope to the ring 30 and also serves to clamp a flexible rubber tube 4I to the telescope. 35

The rubber tube 4I extends rearwardly from the telescope, through the aperture 2l in the plate 20, and terminates in an outwardly extending flange 42. This flange 42 is clamped to the plate 20 by means of a ring 43 and pins or rivets 44 which extend through the ring 43, the flange 42 and the plate 20.

In order to adjust the telescopes to any desired vertical angley the screw 26 is loosened andthe telescopes turned to the desired angle, and the screw v2li is then tightened to clamp them in that position. The telescopes can also be moved toward and from each other and clamped in position by the screws 3l'. This last adjust- 50 ment permits accommodation for diierent interpupillary distances. Regardless of the adjustment however, the flexible rubber tube 4l maintains a light tight and wind tight connection between the goggle and the telescope. s

In the modification shown in Pig. 7, the goggle structure. the telescopes andthe telescope supporting means are the same but the oval-shaped member l is omitted. The lens 45 is carried by the grooved portion l5 of the frame member il and is formed with an aperture Il. The ilexible rubber tube l1 extends through the aperture I5 and has two parallel ilanges 4l and I3 for; gripping the opposite faces of the lens 45 at the aperture I5. In the modification shown in Figs. 8 and 9 the. two eye units each comprise a split frame member Il carrying a sponge rubber pad Il. The frame members Ii are pivotally connected by a bridge 55.

The frame members Il are provided with a grooved portion I5 in which is mounted an ovalshaped member 5I similar to that shown in Fig. 6. The member 5I comprises the rim portions 52, 5I and 5I which are grooved to carry a lens 55. A plate 55 having an aperture 51 is secured to the rim portions 52, 53 and 54 and carries an extension 58 to rwhich a bracket I3 is pivoted at 59. The split ring 24 is secured to this bracket and the adjustable telescope mounting is identical with that of the preceding modifications. The flexible rubber tube 4I extends through the aperture 51 and is fastened to the plate 56 by a ring I3 and pins or rivets 44 as in the modification shown in Figs. 1 and 2.

This last form of my invention is applicable to any type of standard goggle as it is independent of the form of bridge used in the goggle. The oval-shaped members 5I are the same size and shape as the standard goggle lens and the bracket I3 is carried by the oval-shaped members.

It is thus apparent that I attain the objects of my invention and provide a new and improved telescope goggle in which the telescopes are adjustably carried by the goggle frame and a light tight and wind tight connection is maintained between each telescope and its adjacent lens. Obviously various modiiications can be made without departing from the scope of my invention.
